TVLine has learned that Ryan Kennedy (Hellcats, currently on Defiance) will guest-star on the TNT drama in Season 3’s ninth episode, titled “Sweet Revenge,” as Ricky Raydor, a Stanford grad and software engineer who is on the verge of his first buyout (for a company he started with his friends). Described as “smarter than he is wise,” Ricky has come home to weigh in on some of his mother’s recent personal decisions — namely, the possible legal adoption of her ward Rusty.

“Ricky is maybe not as thrilled about the potential little brother as Sharon is about the addition of a son,” series creator James Duff previously told TVLine. “I think we could fairly say that Rusty is the little brother Ricky never wanted.”

In fact, as scooped by my Inside Line column, Ricky is rubbed so much the wrong way by his prospective new sibling that his psychoanalysis of his mother’s motives will subject him to quite the verbal beat-down.
